Surely when you are creating your Art or writing your Story, you are using the Otherworld example.
I was about to say yes, that the "otherworld perception" helps facilitate art (I think to some extent this is true). But a thought occurred to me, that intuition comes in the interpretation of art. To create art there's no "special perception" necessary, just a bit of creativity, but to understand where it comes from and what it is trying to say is something else. We can create something but have no insight into it (it's just an "interesting piece of art"), or we can have a sense of its significance via intuitive perception.
Sometimes insight isn't necessary, sometimes something deep down just needs expression. It's significance comes later, or not.
The person looking at your Art or reading your Story is in the Fiction Zone?
The artist (as I know my art, and my conception of the "Fiction Zone") has to enter into the Fiction Zone. Perhaps what I have written above, and even the name I chose "Fiction Zone" are a bit misleading.
For me, to enter into the Fiction Zone is an artistic and creative experience, otherwise I wouldn't be able to create art the way I do.
I think this requires another blog.
